摘要: The kinetics of the electron transfer between NADH and ferrocenecarboxylic acid (FMCA) catalyzed by diaphorase from Clostridium kluveri (EC 1.8.1.4.) was studied voltammetry. A commercially available digital simulation program permitted one to determine rate constants catalytic system a fitting procedure. constant 3×104 M−1 s−1was found for reaction mediator while value 8 M−1 s−1was parallel competitive mediator. In addition comparison present method other data treatment procedures reported in literature brief evaluation their limits applicability were carried out.
